Source Water Assessment Program (SWAP) Results T he North Carolina Department of Environment and Natural Resources (DENR), Public Water Supply (PWS) Section, Source Water Assessment Program (SWAP) conducted assessments for all drinking water sources across North Carolina. The purpose of the assessments was to determine the susceptibility of each drinking water source (well or surface water intake) to Potential Contaminant Sources (PCSs). The results of the assessment are available in SWAP Assessment Reports that include maps, background information, and a relative susceptibility rating of Higher, Moderate, or Lower. The relative susceptibility rating of the water source for the Town of Cary was determined by combining the contaminant rating (number and location of PCSs within the assessment area) and the inherent vulnerability rating (i.e., characteristics or existing conditions of the well or watershed and its delineated assessment area). The complete SWAP Assessment Report for the Town of Cary (PWSID# 03-92-020) may be viewed on the internet at: http://www.ncwater.org/pws/swap. Please note that because SWAP results and reports are periodically updated by the PWS Section, the results available on this website may differ from the results that were available at the time this CCR was prepared. To obtain a printed copy of this report, please mail a written request to: Source Water Assessment Program – Report Request, 1634 Mail Service Center, Raleigh NC 27699-1634, or an email request to swap@ncdenr.gov. Please indicate your system name, PWSID, and provide your name, mailing address, and phone number. If you have any questions about the SWAP report, please contact the Source Water Assessment Program staff by phone at (919) 707-9098. It is important to understand that a susceptibility rating of "higher" does not imply poor water quality, only the systems' potential to become contaminated by PCSs in the assessment area. SUSCEPTIBILITY OF SOURCES TO POTENTIAL CONTAMINANT SOURCES (PCSs) SOURCE NAME SUSCEPTIBILITY RATING SWAP REPORT DATE Jordan Lake Higher July 2015 What Causes the Pink Growth on Bathroom Fixtures? T he reddish-pink color frequently noted in bathrooms on shower stalls, tubs, tile, toilets, and sinks is caused by the growth of the bacterium Serratia marcesens. Serratia is found naturally in soil, water, and plants, and carried on animals and humans. The bathroom provides a perfect environment (moist and warm) for the bacterium to thrive. To remove the growth, the best solution is to continually clean and dry the involved surfaces to keep them free from bacteria. Chlorine-based compounds work best, but keep in mind that abrasive cleaners may scratch fixtures, making them more susceptible to bacterial growth. Chlorine bleach can be used periodically to disinfect the toilet and help to eliminate the occurrence of the pink residue. Keeping bathtubs and sinks wiped down using a solution that contains chlorine will also help to minimize its occurrence. Partnership for Safe Water W e're proud to report that, once again, in 2016 the Cary/ Apex Water Treatment Facility was awarded the Partnership for Safe Water's Directors Award for its efforts to achieve excellence in water quality. This marked the thirteenth consecutive year the facility has received the award. The Partnership for Safe Water is a national volunteer initiative developed by EPA and other U.S. drinking water organizations representing water suppliers striving to provide their communities with drinking water quality that surpasses federal standards. The Directors Award is presented to water systems who have completed a successful review in the Partnership's Self-Assessment and Peer Review phase, a phase in which utilities examine the capabilities of their treatment plant operation and their overall water utility administration and then create a plan for implementing improvements. The Town is also a charter member of the Partnership for Safe Water's Distribution System Optimization Program. The goal of this program initiated in 2011 is to further improve and ensure the highest quality drinking water for Cary customers by taking steps to optimize our water distribution system operations and management.
